Question

我对导致这种情况的原因感到难过。我在所有功能测试中得到此错误和堆栈跟踪，我称之为“post”。这是完整的堆栈跟踪：

  7) Error:

这是我正在运行的测试：

 def test_should_validate
    post :validate, :user => { :email => 'quire@example.com',
      :password => 'quire', :password_confirmation => 'quire', :agreed_to_terms => "true" }
    assert assigns(:user).errors.empty?
    assert_response :success
  end

Answer 1

您使用参数UsersControllerTest调用test_should_validate，但您的test_should_validate函数被定义为不接受参数。

Answer 2

原来gattaca gem破坏了我的功能测试，并且是造成这个错误的原因。

为什么我在运行rails功能测试时得到“ArgumentError：错误的参数数量（1表示0）”？
